'Application filed January 12, 1921. Serial No. 4:36,!232.

To all whom it may concern Be it known that I, JAMES S RINEHART,

a citizen of the United States, residin at hereinafter described and definitely claimed.

In the accompanying drawings, forming part hereof:

Figure 1 is a plan view of the sewer pipe joint cleaner constituting the best practical embodiment of my invention of which I am cognizant.

Figure 2 is a cross section through the blade and handle of my novel cleaner in the plane indicated by the line 22 of Figure 1.

Figure 8 is a view illustrating the arrangement of my novel cleaner in a sewer that is being laid when the cleaner is to be manipulated for the removal of excess protruding cement at the inner side of a joint.

Figure 4 is a plan View of a modified sewer pipe joint cleaner.

Figure 5 is a detail longitudinal section taken in the plane indicated by the line 55 of Figure 1-.

Similar numerals designate corresponding parts in Figures 1 to 3 to which reference will first be made.

Because of the pro-vision of my novel sewer pipe joint cleaner it is feasible to disis completed. In this way pense with jute in the making of the joints between the pipe sections 1 shown in Figure 3.

In my mode. of procedure the sewer pipe layer spreads a quantity of mortar in the bottom of the bell of the last laid pipe section, and then inserts the spigot end of another pipev section into the said bell and pushes the said spigot end into the bell as far as possible. This brings about a good joint at the bottom of the pipe. The operator then properly Egrades the pipe, and then applies cement mortar to the side and top of the pipe until the outer side of the joint a tight Water proof joint is formed, but the making of the said joint is attended by cement mortar protruding into the pipe from the joint and forming an obstruction which diminishes the bore of the pipe and renders the same likely to be stopped up by sewage after a short period of use.

My novel implement is designed to enable the operator to expeditiously and easily remove the said inwardly protruding portion of cement at the joint.

The improved implement comprises a handle 2, and a broad blade 3; the'said blade being of steel or other appropriate material, and the handle being by preference of metal. The blade'3 is slightly convex at its side that is to be opposed to the wall of the pipe, in conformity of the curvature of the pipe, and for the sake of lightness the opposite side of the blade is concave. The concave side of the blade is arranged at its longitudinal center against the flattened portion 4 of thehandle 2, and is riveted or otherwise fixed to the said flattened portion. When rivets such as 5 are employed to effect the said con nection the said rivets are preferably countersunk in the convex side of the blade so asto form no projection from said side.

In the practical use of the implement described the implement is introduced as shown in Figure 3 through the end of the last laid pipe section and the implement is manipulated longitudinally and also laterally so as to remove and scrape up the surplus cement mortar, after which the implement is withdrawn from the last laid pipe section, and the pipe is left free of inwardly protruding cement mortar.

In the modification shown in Figures 4 and 5 the blade 3 is slightly curved in the direction of its width and is provided on its forward end with a flange 3 The opposite end 3 of the blade is the cutting or scraping edge, and the flange 3 is designed to retain the removed surplus cement mortar on the blade 3 incident to the removal of the blade from the pipe. The said blade 3 is connected with the handle 2 through the medium of a bail 2 In use of the modified implement it is correctly placed relatively to the annulus of inwardly protruding cement mortar and is then drawn rectilinearly outward when the mortar will be retained in and on the blade 3 and will be drawn with the same out of the pipe. Manifestly the blade 3 may be worked at various points in the pipe so as Emu to remove protruding cement from the bottom sides and top of a joint.

Having described my invention, What I claim and desire to secure by Letters-Pat a ent, is

1. A sewer pipe joint cleaner, comprising a blade slightly curved in the direction of end'of the blade, whereby the blade extends forward laterally at opposite sides of the 15 portion of the handle.

2. seyver pipe joint cleaner comprising a bladecurved in the direction of its Width and having a flange at its forward end and also having a cutting edge at its rear end a handle in alin'ement with the longitudinal center of the blade and in a substantial plane above and in parallelism to the plane of the major portion of. the blade, and a bail carried at the forward end of the handle and directly and fixedly connectedto thecblade atpointshadjacent to the side edges of the blade.

In testimony whereof I aflix my signature.
